What are the two types of Chemistry?
Biological (living) and physical (nonliving)
What type of science is Chemistry?
Define Chemistry
The study of the composition, structure and properties of matter and the changes it undergoes
What can X-rays be used for?
To look at microstructures
What can the patterns that appear with X-rays be used for and what are they called?
X-ray diffraction patterns, and they can be analyzed to be revealed the arrangement of atoms, molecules, and other particles
What can we learn about learning about microstructures?
Chemists can explain the behavior of microstructures
What is a microstructure?
The visible things around us.
What is Organic Chemistry?
The study of carbon-containing compounds
What is Inorganic Chemistry?
The study of those things not classified as organic
What is Physical Chemistry?
The study of properties and changes of their matter in relation to their energy
What is Analytical Chemistry?
The identification of components and composition of materials
What is Bio Chemistry?
The study of substances and processes occuring in living things
What is Theoretical Chemistry?
The use of mathemetics anc computers to understand principles behind obseved chemical behaior to design and predict the properties of new components
What is a Chemical?
Any substance that has a definite composition
What is Basic Research?
Reaserch carried out for the sake of increasing knowledge. Change discoveries are a result of this
What is Applied Research?
Generally carried out to solve a problem. Driven not simply by curiou=sity but the desire to solve a specific problem
What is Theoretical Development?
Involves the production and use of products that improve our quality of life. Often lag far behind basic descoveries
What is Volume?
The amount of space a 3D object occupies. All matter has volume
What is Mass?
The measure of matter
What is Matter?
Anything that has mass or takes up space
What is an atom?
The smallest unit of an element that maintins the properties of that element
What is an element?
A pure substance made of only one kind of atom
What is a compound?
A substance that is made from atoms of two or more elements that are chemically bonded (H20)
What is a molecule?
The smallest unit of an element or coupound that retains all the properties of that element or compound
What can properties help determine?
The identity of an unknown substance, but comparisons of several properties must be made
What is an extensive property?
A property that depends on the amount of matter present (volume, mass, amoutn of energy)
What is an intensive property?
A property that does not depend on matter (melting point, bioling point, density, ability to conduct electricity)
What two categories can properties be put into?
Chemical and physical
What is a physical property?
A characteristic that can be observed or measured without changing the identity of the substance
What do physical properties describe?
The subject ittself, not what it can change into.
